    1-5. Operation Do not disconnect the grounding/earthing conductor cable on the UPS or the building wiring terminals under any circumstance. The UPS system features its own, internal current source (batteries). The UPS output sockets or output terminal blocks may be electrically live even if the UPS system is not connected to the building mains/live wires.
